Question

What is the Mole concept? Give answer in briefly.

Answer 1

Mole concept is one of the fundamentals of the Physical Chemistry.

It is used to make you understand the basics of moles.

To make the calculations simpler, the mole was defined. When dealing with particles of the size of atoms and molecules, it becomes very difficult to do the calculations as they are present in very large numbers.

Mole is the unit of measurement for the amount of substance. This is one of the International System of Units (SI). 

1 Mole is just a number whose value is equal to the Avagadro’s number i.e. 6.022 x 10^23.

Also,
A mole can also be defined as the amount of substance that contains as many atoms, molecules, ions, electrons or any other elementary entities as there are carbon atoms in exactly 12 gm of.
The number of atoms in 12 gm of is called Avogadro’s number.

Applications of mole concept in day to day life:
Calculating number of moles is very useful in
1. Drugs and medicine field
2. Batteries
3. Combustion

Answer 2

Hey mate!

Here's your answer!!

1⃣Mole is the measurement in chemistry. It is used to express the amount of a chemical substance.

2⃣One mole is defined as the amount of substance of a system which contains as many entities like, atoms, molecules and ions as there are atoms in 12 grams of carbon - 12".

3⃣Avogadro number ⤵️⤵️⤵️

The number of the particles present in one mole of any substance = 6.022x1023. This is called avogadro’s number or Avogadro’s constant.

No. Of particles in 1 mole:

1 mole of hydrogen atoms represents
6.022 × 1023 hydrogen atoms.

1 mole of hydrogen molecules represents 6.022 × 1023 hydrogen molecules.

1 mole of water molecules represents
6.022 × 1023 water molecules.
